2. Aim the device at the highest point (A) and briefly press the
Switch-on/measurement button (5) once again.
Make sure to hold the device as steady as possible and place
it level on the ground with the two rear edges. The position
at the two rear edges must not be changed during the
measurements!
– Both measurement and calculation are effected.
– The horizontal (1st line) and vertical (2nd line) distance
values are indicated in the upper measurement value
display.
– The line segment to be determined is displayed as result in
the lower measurement value display (20).
If the inclination angle amounts to more than 45° and is not
indicated in the upper measurement value display, please
proceed as follows:
1. Indirect height measurement is active and the inclination
angle lies outside the measuring range, i.e. ----- will be
indicated in the upper measurement value display instead of
a number.
– The symbol for indirect measurements is displayed.
– The hypotenuse flashes.
2. Activate the inclination display by pressing button 7 for a long
time.
– The inclination angle will be indicated on the display (21).

horizontal distance.
– The second measured value will be indicated in the second

Twofold indirect height measurement
This method is suitable for e.g. height measurements.
The following method applies to inclination angles of less than
45° in relation to the horizontal:
1. Briefly press the Button for indirect measurements (7) twice.
– The symbol for indirect measurements appears on the
display.
– The inclination angle is displayed in the second line of the
upper measurement value display on the right-hand side
(see example 31.1°).
– The bar with number 1 (hypotenuse) flashes.

2. First, aim the device at the highest point (C) and briefly press
the Switch-on/measurement button (5) once to perform a
measurement. In doing so, hold the device as steady as
possible. The alignment of the device in relation to the
reference point must not be changed during the
measurements!
– The first measured value will be displayed in the upper
measurement value display.
3. Aim the device at the lowest point (A) and briefly press the
Switch-on/measurement button (5) once to perform a
measurement.
– The second measured value will be indicated in the third
line of the upper measurement value display.
– The angle will be indicated in the second line of the upper
measurement value display.
– The line segment to be determined is displayed as result in
the lower measurement value display (20).
